Ever wished you could search the Hebrew Bible or Greek New Testament by morphological features — without buying expensive software? Parabible is a free, open-source, browser-based tool that lets you read and search the original languages of Scripture with remarkable sophistication.^1 Built on morphologically parsed and tagged texts, it displays the BHS (Hebrew), Rahlfs LXX (Greek Septuagint), SBL Greek NT, and NET English translation side by side.^2
Click any word in the original language and Parabible reveals its part of speech, tense, person, number, gender, and semantic domain. From there, you can build multi-term searches across phrases, clauses, sentences, or entire verses — filtering by specific books to narrow your results.^2 Under the hood, the search engine uses Clickhouse (an OLAP database) with a custom Rust-based function for blazing-fast queries across the full biblical corpus.^3
Parabible was created by James Cuénod, who holds a PhD in Biblical Theology (Old Testament) from Wheaton College and now serves as Senior AI Translation Technologist at Seed Company, where he consults on AI tools for Bible translation projects.^3 He originally built the tool to help with his own exegetical research, and the entire codebase is open source on GitHub.^4
